Abstract: This original invention, the GRIP-OPERATED NAIL CLIPPER, is a device improving the common (Finger-Operated) Toe-and-Finger Nail Clipper. The invention is the solution to the problem that less dexterous children, aged people, and arthritic and otherwise handicapped people have in manipulating and working the common finger-operated nail clipper. Its simple lever-clamplike action puts the focus of grip-pressure closer and over the nail to be clipped making it easy to control, and the grip action of all five fingers and the palm is much stronger than the normal two-finger common nail clipper. Furthermore, the leverage is increased thus reducing considerably the force necessary to nip the nails clean. Unlike plier-like and other modes of nail clipper where the operating handgrip is opposite the fulcrum hinge and away from the nail being clipped, this invention device works in the direction toward the nail.

Abstract: A method and apparatus for controlling the drying of lumber and the like. During drying, the weight of a lumber charge is continuously monitored to indicate both total weight loss and rate of weight loss. These data are employed, either automatically or manually, to adjust drying action so as to control the moisture-removal rate, and to stop drying action when the desired terminal dryness is reached. Multi-point weight monitoring is used to provide localized moisture-content data. The latter data is used further to adjust drying action so as to promote uniform moisture levels throughout a charge during drying.
